RAIL-SUPPORT.

Specification of Letters Patent.

Patented Mar. 3), 1915.

Application filed August 31, 1914, Serial No. 859,298.

T0 all whom t may concern:

Be it known that I, MARTIN SPRINKMAN, a subject of the Emperor of Germany, who has declared his intention of becoming a citizen of the United States, and residing at Los Angeles, in thecounty of Los Angeles, State of California, have invented a new and useful Rail-Support, of which the following is a specification.

My invention relates to rail supports and particularly to a support to be used in connection with concrete ties.

One of the main objects of my invention is to provide a rail support of the character described, of simple form and construction, in which the use of bolts for the purpose of securing the tie to the support is eliminated. Another object of my invention isl to provide a rail support of the character described, parts of which are so arranged that the same may be accommodated to support rails of different sizes and thicknesses.

Referring to the drawings which are for illustrative purposes only: Figure 1 is a plan view, partly in section, of the tie having rail supports thereon embodying a form of my invention. Fig. 2 is a cross sectional view on line w2-m2 of Fig. 1. Fig. 3 is a perspective view of one end of a tie. Fig. 4 is a perspective view of the chair. Fig. 5 a perspective view of a locking wedge.

the spacer. The rail support forming my invention is particularly designed to be used in connection with a concrete tie, and referring more particularly to the drawings, l designates a. concrete tie which is formed of a shaped piece of metal indicated at 2, the same being filled with concrete as indicated at 3. rlhe ends of the metal cover 2 of the tie extend downwardly and outwardly, terminating in a toe or projection 4 below the body of the concrete 3 for the purpose of better anchoring the tie in the road bed indicated at 5. The metallic cover 2 eX- tends over the sides, end, and upper face or top of the body of concrete 3, and adjacent to each end of the tie the metal cover on the top of the tie is bent to form two parallel lianges indicated at 6, each provided with an undercut inner face designated at 7. The flanges 6 are adapted to receive a chair 8 formed of suitable metal, the chair being provided at each side thereof with an outwardly diverging end face 9 adapted to eX- tend under the flanges 6 and engage the inner faces 7 thereof, thereby preventing an upward dislodgment of the chair S from the face of the tie. For the purpose of preventing longitudinal movement of the chair 8 on the tie set screws 10 are provided which extend through the chair into the metal cover 2.

11 designates a rail, the base of which rests upon the upper face 12 of the chair 8.

13 and 14 designate inwardly extending projections on the upper face of the chair thereby forming a. recess for the reception of the rail heretofore referred to. The inner face of the projection 13 is inclined with relation to the web of the rail and is provided with a series of serrations or teeth indicated at 15.

16 designates a spacer having an inclined face corresponding to the inclined face of the projection 13 and being provided with teeth 17 adapted to engage the teeth on the projection 13. The spacer 16 is provided with a toe 18 which extends under the projections 13 and which lays on one of the flanges of the rail 11, the toe being also provided with a iiange or rib 19 on the under face thereof adapted to engage a slot 20 formed on the upper face of the recess in the chair 8, the rib 19 being for the purpose of preventing the disengagement of the spacer 16 from the teeth of the projection 13 when the rail is removed from the chair. The inner face of the projection 14, indicated at 22, is beveled in approximately parallel direction to the inner face of the toe 18 and is adapted to be engaged by the outer inclined face 23 of a locking wedge 24, the inner face 25 of which engages one side of the rail 11. The under face of the locking wedge 24: rests on the upper face of one flange of the rail 11 and Vis provided with a toe 26 which extends under the projection 14 in a longitudinal groove provided for that purpose.

30 designates a head formed on the spacer 16 to provide means for dislodging the spacer from the chair in the event that the same becomes stuck together through the process of wedging action or rusting which may take place.

The manner of setting up a rail with the fastening device above described is as follows: The chair 8 is placed on the tie, and if so desired is secured thereto by means of the screws 10. The spacer is then placed in engagement with the inner face of the prolines on the upper face of the projection 13, the said lines being arranged to indicate the weight of the rails, that is, for a light rail the spacer would be moved so as to provide a greater width of the spacer in between the inner face of the projection 13 and the rail to be placed upon the chair, and the heavier the rail the less width of spacer being placed between the inner face of the projection 13 and the rail. After the spacer is properly placed the rail is set on the chair and the locking wedge 24 driven into place by any suitable means thereby wedging the rail against the spacer, the wedging action taking place between the rail and the inner face of the 'projection 14.

I claim as my invention:

1. In combination with a concrete tie, a metal cover for said tie, flanges formed on the top of said tie, a chair secured between said flanges on the top of said tie said chair having a recess formed therein, projections extending into said recess from the sides of said chair one of these projections having teeth formed thereon, a spacer having cooperating teeth formed thereon and adapted to be secured between a rail in said recess and said toothed projection, and a locking wedge adapted to be secured between the Copies of this patent may 'ne obtained for ve cents each, bjr addressing the Washington, D. 0

other side of said rail and said plain projection 13, the small vend `of the spacer eX- tending vto certain markings or indicating jection.

2. In combination with a concrete tie, a metal cover for said tie, flanges formedon the top of said tie, a chair secured between said flanges on the top of said tie, said chair having a recess formed therein, projections extending into said recess from the sides of said chair, one of these projections having teeth formed thereon, a spacer secured in said recess between a rail placed therein and said toothed projection, and a locking wedge adapted to be secured between the other side of said rail and said plain projection, said spacer comprising a face adapted to fit against the flange and base of the rail, a back having a series of projections l formed thereon, and a bottom having a rib formed thereon adapted to engage aslot formed in the bottom of the chair.

In testimony whereof, I. have hereunto set my hand at Los Angeles, California, this 1 August, 1914. Y MARTIN SPRINKMAN. Y In presence of- FRED A. MANsFmLD,
